Hello !
I can't figure it out how to connect multiple insert transactions on one page?
For example - I want to upload images from page with different categories(have menu list) and insert by the one button all the images at once.

Yes it's one database entry, it's the submission process for the artists-
first page they register contact info(info table), next page they need to upload images and choose for with one category (5 image total, images table) and after press insert button redirect to another page! I just trying to explain to you what I want to accomplish , if it's will help you to help me :)!

What you are asking for is very possible to make with ADDT but if you are totally unfamiliar with ADDT you should probably go over the manual to go over the many functions that ADDT offers. You can find the manual two ways.

1. After you have created your site and created one blank page you can open the page to have the Developer Toolbox Tab un-greyed out. Then you can click on the last icon (Control Panel) and press the help button.
That will open up the manual.
